Don't try this at home

Yowch. And this is after I'd "reset" the bonnet with a sledgehammer.

Caused by the bonnet being forced open by a freak gust of wind while high, high up on a bridge over the River Clyde. It's also possible that the safety catch (the second-level of bonnet securing) had failed, though it was hard to tell after the poor thing had been yanked open.

It took me quite a few slow-motion microseconds to appreciate that I had just hit... my own car. Initially, the HUGE thump (I was doing 70 mph or so) made me think I'd hit maybe a deer (not an unlikely event out there) or even that another car had flipped across from the other carriageway.
